2. 2
Tissues and types
What is a tissue?
group of cells with similar structure and
function ТТТ
Histology: Histo. Mean Tissue. Logy mean.
To Study.
So the study of tissues is called Histology

3. 3
Types of tissues
1. Epithelial Tissue
2. ConnectiveTissue
3. MuscularTissue
4. Nervous Tissue

4. 4
Epithelial tissue
Location:
- cover body (internal and external)
- Ex. Skin, kidney, trachea, glands,
etc.

5. 5
Characteristics:
- cells close together (very little extracellular
matrix)
- form most glands
- have free surface
- Basal surface:
attaches epithelial cells to underlying
tissues

7. 7
Functions of Epithelial tissues

5.
Protect:
Ex. Skin
Act as a barrier:
Ex. Skin keeps bacteria out
Diffusion and
Filtration:
Ex. Lungs and kidneys
Secretion:
Ex. Sweat glands
Absorption:
Ex. Small intestine

8. 8
Types of Epithelial Tissues
Simple Epithelium
Structure: 1 layer of cells
Stratified Epithelium
Structure: many layers of cells

Connective Tissues
Characteristics
Cells far apart

Contain large amounts of extracellular matrix
ͼ they aren't closely packed they openly
packed

12. 12
Functions of Connective
Tissue
1. Connect tissues:
Ex. Tendons: connect bone to muscle
Ex. Ligaments: connect bone to bone
2. Support and Movement:
Ex. bones

13. 13
3. Storage:
Ex. bones store calcium and adipose
tissue stores fat
5. Transport:
Ex. Blood(also fluid conective tissue)
7. Protect:
Ex. Immune cells

14. Cartilage
Type of connective tissue
Composed of chondrocytes
Contains collagen
Withstands compressions
Provides support, flexibility,
strength
14

15. 15
Types of Cartilage
Hyaline cartilage
Location: covers ends of bones
Structure: some collagen fibers
Function: reduces friction (cushion)
Fibrocartilage
Location: between vertebra
Structure: lots of collagen fibers
Function: can withstand compression

16. 16
Elastic cartilage
Location: ear and tip of
nose
Structure: elastic fibers
Function: can recoil

17. 17

18. {Muscular Tissue }
18
Muscle type
Skeletal
Cardiac
(heart)
Smooth
With the help of muscular tissue we
are able to move

Nervous Tissue
Consist of neurons or nerve cells
Found in brain, spinal cord, and peripheral
nerves
Controls and coordinates body movements
Includes axons, dendrites, cell bodies
